OFTO
Offshore Transmission Owners (OFTOs) operate and maintain offshore electric power transmission infrastructure in Great Britain, delivering electrical power from offshore wind farms to the National Grid. OFTOs may design and build this transmission infrastructure, but in most cases wind farm developers construct the electrical transmission assets and then sell them to an OFTO once complete. By Rahmatallah Poudineh, Craig Brown, Benjamin Foley, Operation In the British electricity market, different functions of the electricity system are separated, with this practice beginning in the 1980s. The activities of generators, transmission operators, system ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Greater Gabbard Wind Farm
Greater Gabbard is a 504 MW wind farm, built on sandbanks off the coast of Suffolk in England at a cost of £1.5 billion. It was completed on 7 September 2012 with all of the Siemens SWT3.6–107 turbines connected. Developed as a joint venture between Airtricity and Fluor, it is now jointly owned by SSE Renewables and Innogy. A 336 MW extension of the wind farm called Galloper was commissioned in April 2018. History Development rights were secured from the Crown Estate in 2003. The project was originally developed by Greater Gabbard Offshore Winds Limited (GGOWL) which was a joint venture between Airtricity and Fluor. Airtricity was subsequently bought by Scottish & Southern Energy who then bought out Fluor's 50% stake. Fluor were contracted to design, supply, install and commission the balance of the plant. Scottish & Southern sold a 50% stake to RWE, the owners of Npower, in November 2008 for £308m. The project was given the go-ahead in May 2008 and wor ...

Robin Rigg Wind Farm
Robin Rigg Wind Farm, Scotland's first offshore wind farm, was constructed by E.ON at Robin Rigg in the Solway Firth, a sandbank midway between the Galloway and Cumbrian coasts. The windfarm first generated power for test purposes on 9 September 2009. The wind farm was completed on 20 April 2010. Description 60 Vestas V90-3MW wind turbines were installed, with an offshore electrical substation. Prysmian provided two 132 kV export cables each 12.5 km long to connect the wind farm to the on-shore substation. Two units were subsequently decommissioned in 2015 due to failures during installation. The 174 MW development provides enough electricity for around 117,000 households. The windfarm employs around 40 people, most of whom are local to the area. It is operated from the Port of Workington. Local suppliers are used whenever possible, providing services including vessel management, fabrication, environmental monitoring, catering, industrial cleaning, in ...

Dudgeon Offshore Wind Farm
Dudgeon Offshore Wind Farm is an offshore wind farm 32 km north of Cromer off the coast of Norfolk, in the North Sea, England. It is owned by Dudgeon Offshore Wind Limited (DOW), a subsidiary of Equinor, Masdar and Statkraft. The site is a relatively flat area of seabed between the Cromer Knoll and Inner Cromer Knoll sandbanks and is one of the furthest offshore sites around the UK. The project included constructing the wind turbines and their foundations, building an offshore substation and an onshore substation at Necton, installing power cables both undersea and onshore, as well as connection to the UK National Grid. This work is estimated to have cost in the region of £1.5bn. The wind farm was fully commissioned in October 2017. The estimated annual production is 1.7 TWh which corresponds to 410,000 homes each using 4,100 kWh/yr.

Hornsea Wind Farm
Hornsea Wind Farm is a Round 3 wind farm which began construction in 2018. Sited in the North Sea off the east coast of England, the eventual wind farm group is planned to have a total capacity of up to 6 gigawatt (GW). The development has been split into a number of subzones. The 1.2 GW Project 1 gained planning consent in 2014. Construction of Hornsea One started in January 2018, and the first turbines began supplying power to the UK national electricity grid in February 2019. The turbines were all installed by October 2019 and the equipment fully commissioned in December 2019. With a capacity of 1,218 MW, it was the largest in the world on its completion. A second 1.4 GW Project 2 was given planning consent in 2016. First power was achieved in December 2021, and it became fully operational in August 2022 overtaking Hornsea One as the largest offshore wind farm in the world.

Electric Power Transmission
Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a ''transmission network''. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery, known as the electrical grid. Efficient long-distance transmission of electric power requires high voltages. This reduces the losses produced by strong currents. Transmission lines use either alternating current (HVAC) or direct current (HVDC). The voltage level is changed with transformers. The voltage is stepped up for transmission, then reduced for local distribution. A wide area synchronous grid, known as an "interconnection" in North America, directly connects generators delivering AC power with the s ...

Beatrice Wind Farm
The Beatrice Offshore Wind Farm now known as Beatrice Offshore Windfarm Ltd (BOWL) project, is a wind farm close to the Beatrice oil field in the Moray Firth, part of the North Sea 13 km off the north east coast of Scotland. History Evaluation project Beatrice Wind Farm Demonstrator Project was a joint venture between Scottish and Southern Energy and Talisman Energy (UK) to build and operate an evaluation wind farm in the deep water close to the Beatrice Oil field that Talisman Energy is planning on decommissioning in the near future. Built in 2007, with two turbines and a total capacity of 10 MW, it was designed to examine the feasibility of building a commercial wind farm in deep water at a reasonable distance from the shore. The jacket foundation design was developed by the Norwegian company OWEC Tower AS, and fabricated in Scotland by Burntisland Fabrications. The site is 13 km from the Scottish coast and in 45 m of water. The evaluation project was proposed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
